Heliatek, an organic thin-film solar cell (OPV) manufacturer in Germany, uses OPV multi-junction cell technology to create solar energy conversion efficiency of 13.2%. The results achieved this time are further proofed by Heliatek's unique technology method for small molecule vacuum evaporation on plastic films. Heliatek also pointed out that the results achieved this time will help Heliatek to achieve an internal roadmap that will increase the conversion efficiency of organic solar cells to 15%, which will help the development of new absorbing molecules (wavelengths from 450 nm to 950 nm). Green light, red/near infrared light, and device structure optimization. Dr. Martin Pfeiffer, chief technology officer of Heliatek, said: “The success this time is based on our chemical research on new organic absorbing materials. The key to our success is thanks to the close cooperation of our research and development teams in physics and chemistry in order to promote the new model. The perfect combination of solar cell design properties." This new record of battery efficiency is said to have been independently measured by the Fraunhofer CSP in accordance with AM 1.5 illumination simulations. (Text/Tina translation) Thrust Spherical Roller Bearing
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction.
Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.

The raceway of the housing washer is at an angle with it`s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.
Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.
The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.
